1912. Serial No. 707,586.

To all whom it may concern! 1 Be it known that I, GEORGE B. BRINK, acitizen of the United States, residing at Plymouth, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in ,Spring Structures, of which the following is a speci'fication.

This invention relates to spring structures.

frame to which the spring su porting wires may be firmly connected an towhich the cover facing may be readily secured.

Another object resides in the provision of a frame for spring stiucturesembodying such characteristics that the stay or supporting wires ma bereadily secured firmly thereto without t e instrumentality of separatefastenings.

With the aboveand other objects in view 25 pointed outin the appendedclaim, it being understood thatchanges may be made in the form, proortion, size and minor details without eparting from the scope orsacrificing any of the advantages of the 0 invention.

In the drawings: Figure 1 is an inverted plan view of a spring structureillustrating my improved base frame. Fig. 2 is a transverse sectionalview of a spring structure my invention and including the upholsterlngmaterial and fastenings. Fig. 3 isan enlarged fra entary sectional view.

Fig. 4 is a view siml ar to Fig. 3 illustrating.

the side facing of the cover secured to the ig. 5 is a fragmentarysectional view of a modification. Fig. 6 is a fragmentary sectional viewillustrating one means for connecting the binding element of the sidefacing to the base frame.

Referring now more particularly to the 'accompanyin drawingsthe'reference characters A an B indicate upper and lower framesrespectively. The upper frame is preferably of wire while the lowerframe is com osed preferably of sheet metal and of an e formationtoprovide side portions 12 an base flange portions 13 with the sideportions 12 preferably directed inwardly to provide an externallongitudinal groove 14, and then directed outwardly to provide aninwardly One object is to provide a novel base' opening longitudinalgroove immediate above the base flangeportion 13. The base flangeportion- 13 of the lower frame B provi es for an ample base for theentire structure and as the flange portion 13 extends entirely aroundthe lower frame it also provides a substantial rest for the ends of thesupporting wires 15. The ends of the sup orting wires 15 are preferablycurved as.

indicated at 16 in Fig. 1 and are secured to the'base flange portions 13fixedly by turning in, as by a welding or other process, the edges ofthe base portions to form binding lips or parts 16.

Arranged between the upper and lower frames are springs 18, the lnnerones may be secured to the supporting wires in any suitable manner andthe marginal ones of which on opposite sides of the structure may besecured to the sides of the u per and lower frames and to the corresponing' supporting wires in any suitable manner, but preferably solely onthe supporting wires and not on the frame.

It is customary to lace upholstering material 19 on the top 0? sprinstructures and over this I dispose a top facing 20 which may be securedto the top of the structure in an suitable manner and the front, backand side facings 21 may besewed or otherwise secured to the top facing20 at 26. There is preferably sewed in the outer or lower edges oftheside facings a wire 22, which is preferably continuous with its endspreferably secured together by means of solder as indicated at 23 inFig. 1. 'If preferred, there may be struck up from the marginal portion12 of the lower base portion a tongue 24 (see Fig. 6) which may extendthrough the side facings 21 and over the edges of this tongue 24, theends of the wire 22 may be bent as indicated at 2?) in Fig. 6. A cord,rope or'other equivalent element may be substituted for the wire 22 solong as it serves the function of providing for an efiicient or novelmeans for holding or drawing the side facings of the cushion at theirouter or lower edges in the external longitudinal groove 14. of the base1% frame.

If it be desired, a bottom facing 27 (see Fig. 5 may be employed tocover the bottom 0 the structure, and if it be used it is sim 1ynecessary to place the edges thereof in t e groove-14 and by virtue ofthe hind ing or clamping action of the cable or'other securing means 22.between-which latter and. the bottom of the groove lel'the'bottom edgesof the facing 27 are disposed, the bottom fag- 1% ing is held securelyin place. The base frame of my strupture, therefore, provides not onlya; base frame for spring structures but also provides means whereby theside facings of the finished article may be socured thereto asmay alsobe secured thereto a bottom facing, if used. It will thus be seen that Iprovide a base frame which is constructed for the ready ap plicationthereto of the side facings of an upholstered cushion and that I alsoprovide an eficient means for securing the spring supporting wires tothe frame. .It will also be seen in the modifid'ation shown in Fig. 5

reemie be secured in said groove 14 of the base frame.

This application is a division of theapplication filed by me'on April25, 1912 for spring structures, Serial No. 693,231.

What isclaimed is A baseframe for spring structures comprisin a memberformed of angle iron with one 0 its portions directed inwardly and 'withits other portion provided with an internal longitudinal groove and alsowith an external longitudinal groove.
